In release builds, there should be no change, but in debug builds the
assert will help us catch undefined behavior resulting from using
util_cpu_caps before it is initialized.
With fix for u_half_test for MSVC from Jesse Natalie squashed in.

A couple of problems were discovered after this series was merged that
cause breakage in different configurations:
(1) It seems that using -mf16c also enables AVX, leading to SIGILL on
platforms that do not support AVX.
(2) Since clang only warns about unknown flags, and as I understand
it Meson's handling in cc.has_argument() is broken, the F16C code is
wrongly enabled when clang is used, even for example on ARM, leading
to a compilation error.

In order to be coherent with the pre-existent functions, this new API
is the one meant to be used when doing half float to float
conversions. It is no more than a wrapper for the softfloat.h API but
we meant to keep that one private.
v2:
- Replace custom f32 -> f16 RTZ implementation with the softfloat
one (Andres).
v3:
- Added API usage clarifying comments (Caio).

v2: use !! in the function to be explicit about type conversion. Though,
gcc generates the same code with or without the logical !!.
